Why it works: Tomato and celery are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,377 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Pickle and finish
Cover all with vinegar and sweeten to taste.
Cut one red pepper and add it to the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peppers
- Form the bulk of the pickle and provide its fresh, vegetal body.
- Tomatoes
- Add moisture and acidity that blend into the pickle's sauce.
- Onions
- Contribute pungency and savory depth once ground into the mixture.
- Vinegar
- Acidifies the mixture, preserving it and giving it its sharp tang.
- Sugar
- Balances the vinegar's sharpness, adding sweetness to taste.
The step that matters
Salting and draining the ground peppers and tomatoes. Salt draws water out of the ground vegetables through osmosis. Draining them thoroughly after standing removes that liquid, so the finished pickle stays firm rather than watery and diluted by the vinegar.
Swap the mace
How well each one fits the dish's main ingredients (pepper, tomato, onion, celery, vinegar, sugar):
- Garlicfits better
- Tarragonfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against pepper, tomato, onion, celery, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
